  • Transport agnostic Websocket library
    I recommend Crow, it's a web framework that supports HTTP and Websockets. It's a bit larger than being only there to just let you compose or decode a packet. But I'm pretty sure everything you mentioned is there already :). Source: about 4 years ago
  • Can I use C++ in the backend ?? Any frameworks there ??
    I've been working on Crow for quite a while now, it's a pretty cool framework IMO. Source: over 4 years ago
  • making a web server in c++?
    If you really want to use C++, check out something like Crow, https://crowcpp.org/ and same thing, you can pass messages between the server and your application. Source: over 4 years ago
